I’ve read your brief and can see that you’d like to develop app with quick turn around. I have 7+ years experience designing and developing apps for both web and mobile.
I would approach your project by starting with wire frames and getting the design completed, before starting the actual development phase. I am highly qualified for this project and would love to speak with you further about taking this project on. If you'd like to view my previous work, take a look at my Freelancer Portfolio.
I do have a few questions about the requirements and would be open to an interview. I will be online for the next 3 hours if you would like to discuss. Otherwise, please let me know what times work for you.
